本申请实施例主要是针对泳池清洁机器人的驱动机构的方式进行改进，以提升泳池清洁机器人的移动效率和清洁效果。在对驱动机构的结构进行说明之前，对泳池清洁机器人的整体结构和工作过程进行简略说明：The embodiments of this application are mainly aimed at improving the driving mechanism of the swimming pool cleaning robot to improve the movement efficiency and cleaning effect of the swimming pool cleaning robot. Before describing the structure of the driving mechanism, a brief description of the overall structure and working process of the swimming pool cleaning robot is given:
图1-图5所示本申请实施例的泳池清洁机器人1主要包括清洁主体10、驱动机构20及清洁滚刷机构30。The swimming pool cleaning robot 1 according to the embodiment of the present application shown in Figures 1 to 5 mainly includes a cleaning body 10, a driving mechanism 20 and a cleaning roller brush mechanism 30.
泳池清洁机器人1通过清洁主体10吸入液体和/或污染物，经过清洁主体10对液体和/或污染物进行过滤，将污染物留在清洁主体10内部，将过滤后的液体重新排入泳池，如此反复，完成对泳池内液体的过滤。驱动机构20与清洁主体10连接，以在泳池清洁机器人1的工作过程中，驱动清洁主体10在泳池内部移动。因此，在清洁主体10对液体进行和/或污染物过滤的同时，随着清洁主体10在泳池内移动，通过清洁滚刷机构30对至少部分泳池表面进行清洁，完成对泳池底部及泳池侧壁的清洗，从而达到对整个泳池进行清洁的目的。 The swimming pool cleaning robot 1 inhales liquid and/or pollutants through the cleaning body 10, filters the liquid and/or pollutants through the cleaning body 10, leaves the pollutants inside the cleaning body 10, and discharges the filtered liquid back into the swimming pool. Repeat this to complete the filtration of the liquid in the swimming pool. The driving mechanism 20 is connected to the cleaning main body 10 to drive the cleaning main body 10 to move inside the swimming pool during the operation of the swimming pool cleaning robot 1 . Therefore, while the cleaning body 10 filters the liquid and/or pollutants, as the cleaning body 10 moves in the swimming pool, at least part of the swimming pool surface is cleaned by the cleaning roller brush mechanism 30 to complete the cleaning of the swimming pool bottom and swimming pool side walls. cleaning to achieve the purpose of cleaning the entire swimming pool.
下面结合附图对本申请实施例的泳池清洁机器人的结构和工作过程进行说明如下：The structure and working process of the swimming pool cleaning robot according to the embodiment of the present application will be described below with reference to the accompanying drawings:
参见图1到图4，本申请实施例的泳池清洁机器人1通过清洁主体10对泳池内的液体和/或污染物进行过滤。清洁主体10包括壳体，用于安装驱动机构20和清洁滚刷机构30等。在一示例中，壳体可以包括上壳体110、活动翻盖120和底壳130。上壳体110与底壳130之间进行连接，且上壳体110相对底壳130可拆卸，便于对清洁机器人1内部的零部件进行清洗或维修。活动翻盖120与上壳体110连接，且活动翻盖120相对上壳体110可转动，便于对清洁主体10内部的部件进行更换、清理。Referring to FIGS. 1 to 4 , the swimming pool cleaning robot 1 according to the embodiment of the present application filters the liquid and/or pollutants in the swimming pool through the cleaning body 10 . The cleaning main body 10 includes a housing for installing a driving mechanism 20 and a cleaning roller brush mechanism 30 and the like. In an example, the housing may include an upper housing 110 , a movable flip cover 120 and a bottom housing 130 . The upper housing 110 and the bottom housing 130 are connected, and the upper housing 110 is detachable relative to the bottom housing 130 to facilitate cleaning or maintenance of the internal parts of the cleaning robot 1 . The movable flip cover 120 is connected to the upper casing 110 , and the movable flip cover 120 is rotatable relative to the upper casing 110 to facilitate replacement and cleaning of components inside the cleaning body 10 .
为了能够吸入泳池内的液体和/或污染物等，清洁主体10包括入水口和出水口10a，出水口10a与入水口分开。例如，清洁主体10的底壳130下方设置有入水口作为进水口，上壳体110设置有出水口10a，并且在清洁主体10内部设置有过滤篮140。泳池中的液体和/或污染物通过位于清洁主体10底部的进水口进入清洁主体10内部，流经过滤篮140，将污染物留在过滤篮内。过滤后的液体通过上壳体110的出水口流出至泳池清洁机器人1外，而重新回到泳池。如此反复，完成对泳池内部液体和/或污染物的清洁过滤。In order to be able to absorb liquid and/or pollutants in the swimming pool, the cleaning body 10 includes a water inlet and a water outlet 10a, and the water outlet 10a is separate from the water inlet. For example, a water inlet is provided below the bottom case 130 of the cleaning body 10 as a water inlet, the upper case 110 is provided with a water outlet 10a, and a filter basket 140 is provided inside the cleaning body 10 . The liquid and/or pollutants in the swimming pool enter the interior of the cleaning body 10 through the water inlet located at the bottom of the cleaning body 10 and flow through the filter basket 140, leaving the pollutants in the filter basket. The filtered liquid flows out of the swimming pool cleaning robot 1 through the water outlet of the upper housing 110 and then returns to the swimming pool. Repeat this to complete the cleaning and filtration of liquids and/or pollutants inside the swimming pool.
可选地，上述进水口设置有单向阀，用以避免流入泳池清洁机器人1内部的水反向流出而影响进水，也防止内部的污染物通过进水口再次泄漏到泳池中。Optionally, the above-mentioned water inlet is provided with a one-way valve to prevent the water flowing into the interior of the swimming pool cleaning robot 1 from flowing out in reverse and affecting the water inlet, and also to prevent internal pollutants from leaking into the swimming pool through the water inlet again.
优选地，在泳池清洁机器人1的行进方向上，前述的进水口位于清洁滚刷机构30的后方。通过这种配置方式，便于使清洁滚刷机构30在清洁主体10的前侧刷起污染物后，被随着清洁主体10移动而随后赶上的进水口吸入，并且在清洁主体10内通过过滤篮对其进行过滤，提高泳池清洁机器人1的清洁效率。Preferably, in the traveling direction of the swimming pool cleaning robot 1, the aforementioned water inlet is located behind the cleaning roller brush mechanism 30. With this configuration, it is convenient for the cleaning roller brush mechanism 30 to brush up contaminants on the front side of the cleaning body 10 , and then be sucked in by the water inlet that catches up with the movement of the cleaning body 10 , and pass through the filter in the cleaning body 10 The basket filters it to improve the cleaning efficiency of the swimming pool cleaning robot 1.
可选地，为了提升泳池清洁机器人1收集污染物的效率，清洁滚刷机构30的转动方向用于将污染物推向进水口。当清洁滚刷机构30的转动方向与泳池清洁机器人10的前进方向一致，便于将被刷起的污染物推向进水口， 进一步提高泳池清洁机器人1的清洁效率。Optionally, in order to improve the efficiency of collecting pollutants by the swimming pool cleaning robot 1, the rotation direction of the cleaning roller brush mechanism 30 is used to push the pollutants toward the water inlet. When the rotation direction of the cleaning roller brush mechanism 30 is consistent with the forward direction of the swimming pool cleaning robot 10, it is convenient to push the brushed pollutants to the water inlet. The cleaning efficiency of the swimming pool cleaning robot 1 is further improved.
当然，在其他方式中，基于清洁滚刷机构30和进水口之间的相对位置关系的不同，清洁滚刷机构30的转动方向也可以与泳池清洁机器人1的前进方向相反，对此不作限制。Of course, in other ways, based on the relative positional relationship between the cleaning roller brush mechanism 30 and the water inlet, the rotation direction of the cleaning roller brush mechanism 30 can also be opposite to the forward direction of the swimming pool cleaning robot 1, and this is not limited.
例如，在清洁滚刷机构30的转动方向与泳池清洁机器人1的前进方向相反的实施例中，进水口可以设置在上壳体110，并且在清洁主体10内设置与进水口对接的抽吸装置。当泳池表面的污染物被清洁滚刷机构30刷起并推向进水口时，可以在抽吸装置的作用下被吸入进水口内，并且通过过滤篮140的过滤后，将污染物留在过滤篮140内以及使过滤后的的液体通过出水口流出至泳池清洁机器人1外，而重新回到泳池。For example, in an embodiment in which the rotation direction of the cleaning roller brush mechanism 30 is opposite to the forward direction of the swimming pool cleaning robot 1, the water inlet can be provided on the upper housing 110, and a suction device docked with the water inlet can be provided in the cleaning body 10. . When the pollutants on the swimming pool surface are brushed up by the cleaning roller brush mechanism 30 and pushed to the water inlet, they can be sucked into the water inlet under the action of the suction device, and after being filtered by the filter basket 140, the pollutants will remain in the filter. The filtered liquid flows out of the basket 140 and out of the swimming pool cleaning robot 1 through the water outlet, and then returns to the swimming pool.
可以理解的是，在本申请的某些实施例中，也可以是同时在清洁主体10的底侧和前侧同时设置进水口来增加污染物的收集效率。在这种实施例中，清洁滚刷机构30可以是但不限于可相对清洁主体10往复转动，例如通过齿轮变向机构在顺时钟转动和逆时钟转动之间进行切换，从而对泳池表面上附着度相对较强的污染物进行清洁程序。It can be understood that in some embodiments of the present application, water inlets can also be provided on the bottom side and the front side of the cleaning body 10 at the same time to increase the collection efficiency of pollutants. In this embodiment, the cleaning roller brush mechanism 30 may be, but is not limited to, reciprocally rotatable relative to the cleaning body 10 , for example, by switching between clockwise rotation and counterclockwise rotation through a gear change mechanism, thereby adhering to the pool surface. Relatively strong contaminants undergo cleaning procedures.
在本申请的一些实施例中，上壳体110的出水口可以使出水方向基本垂直于泳池清洁机器人1的移动平面，这样出水可以为泳池清洁机器人1提供较好的推力，使泳池清洁机器人被压紧在泳池的底面或者侧壁上。不仅可以保证在爬墙(也就是在侧壁上移动)时的可靠性，而且有助于帮助泳池清洁机器人1吸水以提高清洁效率。In some embodiments of the present application, the water outlet of the upper housing 110 can make the water outlet direction substantially perpendicular to the moving plane of the swimming pool cleaning robot 1. In this way, the water outlet can provide better thrust for the swimming pool cleaning robot 1, so that the swimming pool cleaning robot can be moved. Press firmly onto the bottom or side walls of the pool. It not only ensures reliability when climbing the wall (that is, moving on the side wall), but also helps the swimming pool cleaning robot 1 absorb water to improve cleaning efficiency.
除此之外，在泳池清洁机器人1的壳体后方还可以设置一排水口。当泳池清洁机器人1脱离泳池，可以通过该排水口排出泳池清洁机器人1内部的液体，减轻泳池清洁机器人1的重量，便于用户将泳池清洁机器人1拎出水面。In addition, a drain outlet can be provided behind the housing of the swimming pool cleaning robot 1 . When the swimming pool cleaning robot 1 is separated from the swimming pool, the liquid inside the swimming pool cleaning robot 1 can be discharged through the drain port, thereby reducing the weight of the swimming pool cleaning robot 1 and making it easier for the user to lift the swimming pool cleaning robot 1 out of the water.
可选地，排水口设置有单向阀。通过排水口设置的单向阀，可以在泳池清洁机器人1的工作过程中，即进水口吸入泳池内部液体和/或污染物时，保证排水口的密封，避免排水口对泳池清洁机器人的工作过程造成干扰。 Optionally, the drain outlet is provided with a one-way valve. The one-way valve provided at the drain port can ensure the sealing of the drain port during the working process of the swimming pool cleaning robot 1, that is, when the water inlet sucks in liquid and/or pollutants inside the swimming pool, and prevents the drain port from affecting the working process of the swimming pool cleaning robot. cause interference.

A dynamic sealing structure is used between the output shaft and the sealed cabin to ensure that water does not enter the sealed cabin. The output shaft passes through the housing and is docked with the driving wheel 210 of the driving mechanism 20 for transmission.
在本申请实施例中，清洁主体10的宽度方向上的两侧分别设置有一个驱动轮210，这两个驱动轮210相对独立运动。若两个驱动轮210同向、同速运动则可以实现泳池清洁机器人1的前进或者后退。若两个驱动轮210不同速或者不同向运动则可以实现泳池清洁机器人1的转弯。In the embodiment of the present application, one driving wheel 210 is provided on both sides of the cleaning body 10 in the width direction, and the two driving wheels 210 move relatively independently. If the two driving wheels 210 move in the same direction and at the same speed, the swimming pool cleaning robot 1 can move forward or backward. If the two driving wheels 210 move at different speeds or in different directions, the swimming pool cleaning robot 1 can turn.
驱动轮210上设置有履带220。在这种实施例中，驱动轮210包括绕轴心设置的第一外齿圈和绕外周面设置的第二外齿圈212，第二外齿圈212与履带220外啮合，使履带220被第二外齿圈212驱动而带动清洁主体10移动。The driving wheel 210 is provided with crawler tracks 220 . In this embodiment, the driving wheel 210 includes a first external gear ring 212 arranged around the axis and a second external gear gear 212 arranged around the outer circumference.

在上述具体实现方式中，泳池清洁机器人1的驱动电机作为动力源，为驱动轮210和清洁滚刷机构30提供动力，使得驱动轮210和履带220运动，从而带动清洁主体10在泳池内移动。同时，在清洁主体10的移动过程中，清洁滚刷机构30可转动地清洁泳池内底面和侧壁等表面的污染物，以实现对泳池的清洁和净化。In the above specific implementation manner, the driving motor of the swimming pool cleaning robot 1 is used as a power source to provide power for the driving wheel 210 and the cleaning roller brush mechanism 30, so that the driving wheel 210 and the crawler track 220 move, thereby driving the cleaning body 10 to move in the swimming pool. At the same time, during the movement of the cleaning body 10, the cleaning roller brush mechanism 30 can rotatably clean the pollutants on the bottom surface, side walls and other surfaces of the swimming pool to achieve cleaning and purification of the swimming pool.
为了对履带220进行张紧，从动轮230可转动地设置在清洁主体10上。从动轮230与驱动轮210位于清洁主体10的同一侧，并且间隔设置。其中，从动轮230包括第三外齿圈231，履带220的内表面设置有多个配合齿221。当履带220套设在驱动轮210和从动轮230外，履带220的配合齿221分别与第二外齿圈212和第三外齿圈231啮合。这样通过驱动轮210和从动轮 230的前后配合可以对履带220进行张紧，进而保证泳池清洁机器人1移动时的稳定性。In order to tension the crawler belt 220 , the driven wheel 230 is rotatably provided on the cleaning body 10 . The driven wheel 230 and the driving wheel 210 are located on the same side of the cleaning body 10 and are spaced apart.

The first external ring gear includes a first tooth segment 2111. The first tooth segment 2111 meshes with the driving gear 240. When the driving gear 240 rotates, the driving wheel 210 is driven by the first gear segment 2111. Turn.
在一些示例中，如图1所示，清洁主体10上设置有轴杆16，第一齿段2111可以直接套设在轴杆16上，第二齿段2112套设在第一齿段2111上。In some examples, as shown in FIG. 1 , the cleaning body 10 is provided with a shaft 16 , the first gear segment 2111 can be directly sleeved on the shaft 16 , and the second gear segment 2112 is sleeved on the first gear segment 2111 .
在另一些示例中，如图5所示，清洁主体10上设置有轴杆16，第二齿段2112套设在轴杆16上。通过轴杆16可以对第二齿段2112进行可靠支撑和定位。轴杆16内设置有轴承171，轴承171内穿设有支撑杆172，第一齿段2111可以通过轴承171与轴杆16旋转连接。泳池清洁机器人1通过驱动轮210的第一外齿圈的第一齿段2111与驱动电机的主动齿轮240外啮合进行传动，带动驱动轮210的第二外齿圈212转动以实现移动，使得在移动时间一定的情况下，通过直径小的第一外齿圈带动直径大的第二外齿圈212转 动，从而泳池清洁机器人1的移动距离可更远，提升了泳池清洁机器人1的移动效率，从而提升了清洁效率。同时，由于清洁滚刷机构30通过与第二齿段2112外啮合实现滚动。若清洁滚刷机构30的转速与现有技术中的清洁滚刷机构转速相同、进而可保障清洁效果不变的情况下，再若移动时间相同，则清洁滚刷机构30随着泳池清洁机器人1的移动距离变远、清洁的距离则更远，从而使得清洁滚刷机构30的利用率更高，从而一定程度上降低了清洁滚刷机构30的磨损，提升了清洁滚刷机构30的使用寿命。In other examples, as shown in FIG. 5 , the cleaning body 10 is provided with a shaft 16 , and the second tooth segment 2112 is sleeved on the shaft 16 . The second tooth segment 2112 can be reliably supported and positioned through the shaft 16 . A bearing 171 is provided in the shaft 16 , and a support rod 172 is provided in the bearing 171 . The first tooth segment 2111 can be rotatably connected to the shaft 16 through the bearing 171 . The swimming pool cleaning robot 1 is driven by the first tooth segment 2111 of the first external ring gear of the driving wheel 210 externally meshing with the driving gear 240 of the driving motor, and drives the second external ring gear 212 of the driving wheel 210 to rotate to achieve movement, so that in When the moving time is constant, the second external ring gear with a large diameter is driven by the first external ring gear with a small diameter to rotate 212 times. Therefore, the moving distance of the swimming pool cleaning robot 1 can be further, which improves the moving efficiency of the swimming pool cleaning robot 1, thereby improving the cleaning efficiency. At the same time, the cleaning roller brush mechanism 30 realizes rolling through external meshing with the second tooth segment 2112 . If the rotational speed of the cleaning roller brush mechanism 30 is the same as that of the cleaning roller brush mechanism in the prior art, thus ensuring that the cleaning effect remains unchanged, and if the movement time is the same, then the cleaning roller brush mechanism 30 will follow the swimming pool cleaning robot 1 The moving distance becomes longer and the cleaning distance becomes longer, so that the utilization rate of the cleaning roller brush mechanism 30 is higher, thereby reducing the wear of the cleaning roller brush mechanism 30 to a certain extent and extending the service life of the cleaning roller brush mechanism 30 .
在本申请的一些实施例中，驱动轮210的第一外齿圈的第一齿段2111和第二外齿圈212可以同轴设置，且两者之间可以刚性连接。在驱动电机的主动齿轮240带动第一外齿圈的第一齿段2111转动时，使得第二外齿圈212与第一外齿圈的第一齿段2111同轴转动且转速相同；驱动轮210的第一外齿圈的第一齿段2111直径小于第二外齿圈212的直径，使得在相同的转速下，由于第二外齿圈212圆周长度更长，而带动清洁主体10移动的距离更远，从而提升了泳池清洁机器人1的移动速度。在泳池面积不变的情况下，泳池清洁机器人1移动的速度提升，表示清洁一次泳池所需的时间减少，也即提升了清洁效率。In some embodiments of the present application, the first tooth segment 2111 and the second external ring gear 212 of the first external ring gear of the driving wheel 210 may be coaxially arranged, and the two may be rigidly connected. When the driving gear 240 of the driving motor drives the first tooth segment 2111 of the first external ring gear to rotate, the second external ring gear 212 and the first tooth segment 2111 of the first external ring gear rotate coaxially and at the same speed; the driving wheel The diameter of the first tooth segment 2111 of the first external ring gear 210 is smaller than the diameter of the second external ring gear 212, so that at the same rotation speed, due to the longer circumferential length of the second external ring gear 212, the cleaning body 10 is driven to move. The distance is further, thereby increasing the moving speed of the swimming pool cleaning robot 1. When the swimming pool area remains unchanged, the swimming speed of the swimming pool cleaning robot 1 increases, which means that the time required to clean the swimming pool is reduced, that is, the cleaning efficiency is improved.
进一步地，为了保障主动齿轮240对外传输的效率，特别地，主动齿轮240和驱动轮210之间的第一传动比小于第一设定值。其中，第一传动比是指输入齿轮的转速与输出齿轮的转速之比。具体到本示例中，第一传动比可以是主动齿轮240的转速与第一外齿圈转速之间的比值。从第一传动比的定义不难看出，由于主动齿轮240的转速与驱动电机的转速有关，因此，在假定驱动电机的转速不变的情况下，第一外齿圈的转速越高，第一传动比的值越小，也就是说，第一外齿圈的转速越快，清洁主体的移动速度也就越快。Further, in order to ensure the external transmission efficiency of the driving gear 240, in particular, the first transmission ratio between the driving gear 240 and the driving wheel 210 is smaller than the first set value. The first transmission ratio refers to the ratio of the rotation speed of the input gear to the rotation speed of the output gear. Specifically in this example, the first transmission ratio may be a ratio between the rotation speed of the driving gear 240 and the rotation speed of the first external ring gear. It is easy to see from the definition of the first transmission ratio that since the rotation speed of the driving gear 240 is related to the rotation speed of the drive motor, therefore, assuming that the rotation speed of the drive motor remains unchanged, the higher the rotation speed of the first external ring gear, the higher the rotation speed of the first external ring gear. The smaller the value of the transmission ratio, that is, the faster the rotation speed of the first external ring gear, the faster the cleaning body moves.
在一种可行方式中，第一设定值可以为2.5：1(也即5：2)，这一传动比可以保证清洁主体10的移动速度满足要求，不会移动的过慢，且还可以保证清洁效果适中，不会由于移动速度过快导致不能有效清洁。In a feasible way, the first setting value can be 2.5:1 (that is, 5:2). This transmission ratio can ensure that the moving speed of the cleaning body 10 meets the requirements and will not move too slowly, and can also Ensure that the cleaning effect is moderate, and the moving speed will not be too fast, resulting in ineffective cleaning.
在一示例中，驱动电机的主动齿轮240的齿数的取值范围为10～15，例 如为13，第一外齿圈的第一齿段2111的齿数的取值范围为30～35，例如为32。当然，在其他示例中第一设定值可以是其他值。In an example, the number of teeth of the driving gear 240 of the driving motor ranges from 10 to 15. For example, if it is 13, the number of teeth of the first tooth segment 2111 of the first external ring gear ranges from 30 to 35, for example, 32. Of course, the first set value may be other values in other examples.
如图1-3所示。在本申请的一实施例中，第一齿段2111和第二齿段2112沿驱动轮210的轴向自面向清洁主体10的一侧依次设置。第一齿段2111的直径可以是但不限于小于第二齿段2112的直径。As shown in Figure 1-3. In an embodiment of the present application, the first gear segment 2111 and the second gear segment 2112 are arranged in sequence along the axial direction of the driving wheel 210 from the side facing the cleaning body 10 . The diameter of the first tooth segment 2111 may be, but is not limited to, smaller than the diameter of the second tooth segment 2112 .
第二齿段2112被配置为可相对第一齿段2111转动，滚刷齿轮321与第二齿段2112外啮合，并且在驱动轮210转动时，第二齿段2112与第一齿段2111反向转动而带动滚刷齿轮321与驱动轮210同向转动。The second tooth segment 2112 is configured to rotate relative to the first tooth segment 2111. The rolling brush gear 321 is externally meshed with the second tooth segment 2112. When the driving wheel 210 rotates, the second tooth segment 2112 is opposite to the first tooth segment 2111. The brush gear 321 and the driving wheel 210 are rotated in the same direction to drive the roller brush gear 321 to rotate in the same direction.
泳池清洁机器人还包括过渡齿轮250，第一齿段2111通过过渡齿轮250与主动齿轮240啮合。The swimming pool cleaning robot also includes a transition gear 250 through which the first gear segment 2111 meshes with the driving gear 240 .
其中，主动齿轮240分别与过渡齿轮250和第二齿段2112外啮合，过渡齿轮250分别与主动齿轮240和第一齿段2111外啮合。The driving gear 240 is externally meshed with the transition gear 250 and the second gear segment 2112 respectively, and the transition gear 250 is externally meshed with the driving gear 240 and the first gear segment 2111 respectively.
因此，当主动齿轮240驱动过渡齿轮250和第二齿段2112转动时，通过过渡齿轮250驱动第一齿段2111转动，带动驱动轮210转动，以及通过第二齿段2112驱动滚刷齿轮321转动，此时，由于第二齿段2112和第一齿段2111反向转动，使滚刷齿轮321的转动方向调整为与驱动轮210的转动方向一致，以带动滚刷主体310可以朝向进水口的方向同步转动，方便进水口将污染物吸入，以进行清洁过滤程序。Therefore, when the driving gear 240 drives the transition gear 250 and the second tooth segment 2112 to rotate, the transition gear 250 drives the first tooth segment 2111 to rotate, driving the driving wheel 210 to rotate, and the second tooth segment 2112 drives the brush gear 321 to rotate. , at this time, due to the reverse rotation of the second tooth segment 2112 and the first tooth segment 2111, the rotation direction of the roller brush gear 321 is adjusted to be consistent with the rotation direction of the driving wheel 210, so as to drive the roller brush body 310 toward the water inlet. The directions rotate synchronously to facilitate the water inlet to suck in pollutants for cleaning and filtration procedures.
在一种具体实施方式中，主动齿轮240与清洁滚刷机构30之间的第二传动比可以为1：1。第二传动比可以是输入齿轮的速度与输出齿轮的速度之比，也即主动齿轮240的转速和清洁滚刷机构30的转速之间的比值为第二传动比，第二传动比为1：1，则表示清洁滚刷机构30的转动速度可以较高，满足清洁的需求。In a specific implementation, the second transmission ratio between the driving gear 240 and the cleaning roller brush mechanism 30 may be 1:1. The second transmission ratio may be the ratio of the speed of the input gear to the speed of the output gear, that is, the ratio between the rotation speed of the driving gear 240 and the rotation speed of the cleaning roller brush mechanism 30 is the second transmission ratio, and the second transmission ratio is 1: 1, it means that the rotation speed of the cleaning roller brush mechanism 30 can be higher to meet the cleaning requirements.
当然，在其他实施例中，第二传动比可以是其他比值，对此不作限制。Of course, in other embodiments, the second transmission ratio can be other ratios, and there is no limitation on this.
综上，本申请实施例的泳池清洁机器人的清洁滚刷机构与驱动轮外啮合配合，使得清洁滚刷机构能够在不降低转动速度的情况下，使泳池清洁机器人有较高的整体移动速度，以此提升清洁效率。 In summary, the cleaning roller brush mechanism of the swimming pool cleaning robot in the embodiment of the present application meshes with the outside of the driving wheel, so that the cleaning roller brush mechanism can enable the swimming pool cleaning robot to have a higher overall moving speed without reducing the rotation speed. This improves cleaning efficiency.
